Adjust options for help_label_tooltip and help_label_popover

* place tooltip and popover help_label on the same line as the label
* make icon configurable (they were already passed to the view but then hardcoded)
* rename block from help_label_popover_title to help_label_popover and rename block from help_label_tooltip_title to help_label_tooltip to follow the same name schema as the other help_ options
